My invention relates t new and useful ilnprovements in heater assembly. More particularly my invention is directed to the hot water type of automobile heater which comprises a radiator core adapted to receive water from and retlrn it to the cooling system of the automobile engine, and a fan or blower mounted behind it to force air from the car through the radiator core so that it becomes heated.

My invention relates to new and useful improvements in the assembly of the elements necessary for the construction of such a heater.

The principal object of the invention is to provide such a heater which may be easily assembled and taken apart.

Another object is to provide a novel combination of the necessary elements for such a heater that will be positively and firmly held in relative position when assembled, but are individually -easily accessible for replacement or repair. 1

Another object is to provide such a combination that permits the radiator core to be securely held in position without subjecting the delicate parts thereof to undue pressure or stress.

Another object is to provide means for holding elements of the heater in assembled relationship cushioned against shock.

Numerous other objects and advantages of my invention will be apparent from the detailed description of the embodiment shown in the accompanying drawings.

Fig. 1 is a side elevation of such an assembled heater mounted in an automobile.

Fig. 2 is a central vertical section of the heater shown in Fig. 1. 4 Fig. 3 is a partial sectional view along line 3 3 in Fig. 1.

Referring now more particularly to the drawings, wherein like and corresponding parts are designated by similar reference r characters throughout, 1 is theradiator core having headers 2 and 3, with inlet and outlet pipes 4 and 5, respectively extending therefrom, each supported by two walls of its header and having cut-away portions 4a and 5a, respectively, within the headers for sup- HEATER ASSEMBLY 1931.

plying and discharging the water to and from the core. An air vent valve 6 is located in the top header 2. Air deflectors 7 are mounted on a rectangular frame 8 having a rectangular seat 8a adapted to receive 'the edges of one side of the core. A rectangular shell for partially encasing the core is composed of two parts 9 and 10, adapted to snugly it one within the other and be held together by screws 11. Part 9 has a rectangular opening 9a in its face in which the frame 8 [its and through which the air deflectors 7 project, and a circular opening 9b in its top which allows the air vent valve 6 to extend therethrough. Part 10 has two circular openings 100J in its rear Wall through which inlet and outlet pipes 4 and 5 respectively project when the unit is assembled. Onpart 10 of the shell is mounted a bracket 12 which supports the motor 13 which drives the fan 14. There are also mounted on 10 rea-irward- 'ly extending brackets 15 for mounting the unit on the dashboard 16 in any desired manner. Flexible hose sections 17 connect the inlet 4 and the outlet' with the cooling system of the automobile engine. Coil springs 18 are positioned around inlet pipe 4 and outlet pipe 5 and are adapted to be com-` pressed when parts 9 and 10 of the shell are fitted together, thus bearing against the headers 2 and 3 of the core 1 and holding the core securely in position against the frame 8, and the frame 8 securely in position within the edges of the rectangular opening 9a. The screws 11 are adapted to fit within holes in part 9 and to be threaded through corresponding holes in part 10. In this manner the unit is held in assembled position with the springs 18 compressed.

I claim: f

1. A heater ofthe type described comprising a radiator core, a two part shell for partially encasing said radiator core, means for fastening said two parts together and spring means adapted to abut against one of said parts and one side of said core for holding the other side of said Vcore in Contact with said other part. y

-2. A heater of the type described comprising a radiator core having anfupper and lower header', an inlet pipe extending from said upper header, an outlet pipe extending from said lower header, a two part shell for partially enclosing said radiator core, means for fastening said two parts together, and spring means mounted on said pipes for holding said core in position.

3. A heater of the type described comprising a radiator core having an upper and lower header, an inlet pipe extending from said upper header, an outlet pipe extending from said lower header, a two part shell for partially enclosing said radiator core, means for fastening said two parts together and coiled springs mounted on and surrounding said pipes adapted to abut against the headers and one of said parts for holding said radiator core in position in contact with said other part. s

1. A heater of the type described comprising a radiator core having an upper and lower header, an inlet pipe extending from and supported by two walls of the upper header, an outlet pipe extending from and supported by two walls of the lower header, a casing having a rectangular opening for partially enclosing said core, a closure for said casing, a rectangular frame adapted to fit within and extend without said rectangular opening, air deileetors mounted n said frame, means for fastening said closure and said casing together, and coiled springs mounted on and surrounding said pipes between said headers and said closure adapted to hold said frame in position against said casing and said core in position against said frame.

5. A heater of the type described comprising a radiator core, a two part shell for partially encasing said radiator core, means for fastening said two parts together, a frame, air defleetors mounted on said frame, and coiled springs mounted between said radiator core and one side of said shell for holding said frame against the other side of said shell and said radiator core against said frame.

6. A heater of the type described comprising a radiator core, a two part shell for partially eneasing said radiator core, a rectangular opening in one side of said shell, a rectangular frame adapted to fit within said opening, air deflectors mounted on said frame, a seat within said fra-me adapted to receive the edges of one side of said radiator core, means for fastening said two parts together and coiled springs mounted between said core and the opposite side of said shell adapted to hold said frame in position in said opening and said core in the seat in said frame.

7. A heater of the type 4described comprising a radiator core having an upper and lower header, an inlet pipe extending from the upper header, an outlet pipe extending from the lower header, a casing having a rectangular opening, a closure for said casing, a rectangular frame adapted to fit within and extend without said opening, air deflectors mounted on said frame, a fan adjacent said core, a motor mounted on said closure for driving said fan, brackets secured to said closure for mounting said heater, means for fastening together said closure and said casing and coiled springsmounted on and surrounding said pipes between said headers and said elosure adapted to be compressed when said closure is fastened to said casing so as to hold said frame in position within said rectangular opening and said core in position against said frame.
